Area forecast discussion, Apr 23, 2:32 PM EDT, 3 hours 31 minutes before
CENTRAL PENNSYLVANIA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 230 PM EDT TUE APR 23 1996 SHOWER ACTIVITY STARTING TO BLOSSOM OVER THE CTP COUNTIES DURING THE LAST HOUR OR SO. EXCEPTION IS THE LOWER SUSQUEHANNA VALLEY WHERE NO ECHOES HAVE BEEN SIGHTED YET. SO FAR...LDS HAS BEEN QUIET. DID HAVE THE BEGINNINGS OF AN INTERESTING CELL CLINTON COUNTY...BUT IT FIZZLED JUST AS FAST AS IT FORMED. WONDER IF THIS IS AN INDICATION THAT MUCH OF THE AREA JUST ISN/T QUITE RIPE ENOUGH YET FOR DEVELOPMENT OF SVR ATTM. OF COURSE ONCE AGAIN THE EXCEPTION IS THE LOWER SUSQUEHANNA VALLEY WHERE INSTABILITIES GREATEST AND MODERATE SVR IS OUTLOOKED BY SPC. HODOGRAPHS WOULD INDICATE THAT ATMOSPHERE WOULD SUPPORT MULIT-CELL LINEAR TYPE STORMS TODAY WITH BEST POTENTIAL OF SVR COMING FROM STRONG WINDS. CURRENT VAD WINDS AT CTP SHOW SOME VERY SLIGHT VEERING AT LOWEST LEVELS...BUT PROBABLY MORE IMPRESSIVE IS THE 50 KT WINDS AT 8000 FT. IT WILL NOT TAKE MUCH TO MIX GUSTY WINDS TO SURFACE. CELLS ON KCCX HAVE BEEN MOVING AROUND 40 KTS. MODIFIED IAD SOUNDING FOR THIS AFTERNOON SHOWS LI/S IN THE LOWER SUSQUEHANNA VALLEY AROUND -4...BUT LOW LEVEL MOISTURE STILL SEEMS TO BE LACKING SOMEWHAT. BEST 850 JET PROGGED TO BE ACROSS THE AREA NOW...BUT WILL BE WELL TO THE EAST BY 00Z. THIS MAY BE A BIT FAST...AS MODELS HAVE BEEN FAST WITH SURFACE WAVE AND FRONTAL PROGRESS TODAY. THINK BEST TIME TO GET SEVERE WOULD HAVE TO BE SOON...OR WE MAY LOOSE THE BEST DYNAMICS. SAW THE PIT WORK ZONES AND THEY LOOK GOOD. JUNG
